Objective To investigate the diagnostic value of digital breast tomosynthesis (DBT) plus full-field digital mammography (FFDM) in benign and malignant breast disease.Methods The prospective study enrolled 46 consenting women with a clinical suspicious of breast lesion confirmed by pathology. All the patients underwent DBT, FFDM and dedicated breast magnetic resonance image (DB-MRI) examinations before surgery or biopsy. To observe the manifestation of breast disease in different examinations according to breast imaging reporting and data system (BI-RADS), and to evaluate the visibility grade of disease between DBT plus FFDM and FFDM alone. Using receiving operating characteristic(ROC) and Z test to analysis the diagnostic efficiency of three examinations.Results Forty-six cases included 14 benign cases and 32 malignant cases. Compared with FFDM, 35 cases showed increased visibility in DBT plus FFDM, that the malignant lesion manifested mass with speculated and architectural distortion(23/27) and the benign lesion manifested mass with halo sign(6/8). Eleven cases didn't show increase visibility in both DBT plus FFDM and FFDM alone. The ration of BI-RADS 0 in FFDM was 23.9%(11/46), meanwhile in other two examination were 0. The ration of BI-RADS 3 in DBT plus FFDM was the lowest(6.5%, 3/46). When the lesion in DBT plus FFDM showed mass or speculated, in MRI showed similar morphology with mass or mass-like enhancement. According pathology as the gold standard, excluded 11 cases with BI-RADS 0 in FFDM, there was significant statistical difference between DBT plus FFDM and FFDM alone in 35 cases (Z=2.132, P=0.033) to differentiate benign and malignant breast disease, the area of ROC curve were respectively 0.955, 0.878. There is no statistical difference between DBT plus FFDM and MRI in 46 cases (Z=0.502, P=0.616), the area of ROC curve were respectively 0.887, 0.908.Conclusion DBT combined with FFDM can improve both detection of breast lesion and diagnostic efficiency, while the performance value between DBT and MRI are equal.

OBJECTIVE: To study the role of JNK (c-Jun N-terminal kinase) signal transduction pathway on the nasal mucosa remodeling in allergic rhinitis rats, to explore whether IL-1β participates the nasal mucosa remodeling in allergic rhinitis by JNK signal transduction pathway. METHOD: Totally 60 male Wistar rats (weighing about 200-250 g)were randomly divided into A (AR group) and B group (control group). The rats in A group were sensitized for inducing AR by intraperitoneal injection ovalbumin and Al(OH)₃. Ovalbumin was respectively dropped in each nasal cavity of every rat for 4,8,12 weeks(A4,A8,or A12 group) each had 10 rats. The rats in B group were sensitized by intraperitoneal injection saline. Saline was respectively dropped in each nasal cavity of every rat for 4,8, 12 weeks(B4, B8, or B12 group), and each had 10 rats. The concentration of IL-1β in serum and nasal lavage fluid were tested by ELASA. The protein expressions of P-JNK and P-c-Jun were detected by immunohistochemical technique. Linear correlation analysis showed the correlation between levels of IL-1β in serum and P-JNK protein, levels of IL-1β in nasal lavage fluid and P-JNK protein. RESULT: The concentrations of IL-1β in serum and nasal lavage fluid of A group were all significantly higher than those of the corresponding B group (all P < 0.01). Compared with A4 group and A8 group, concentrations of IL-1β in nasal lavage fluid of A12 group were significantly increased (all P < 0.01). However the levels of IL-1β in serum were not significantly different among them (all P > 0.05). Mean absorbance values of P-JNK and P-c-Jun in A group were significantly higher than those in corresponding B group (all P < 0.01) and compared with A4 group and A8 group, those of A12 group were significantly increased (all P < 0.01). Strong positive correlation were found between P-JNK and concentration of IL-1β in serum or nasal lavage fluid (r = 0.835 and r = 0.902, all P < 0.01). CONCLUSION JNK signal transduction pathway plays important role in the nasal mucosa remodeling in allergic rhinitis rats. IL-1β participates in AR nasal mucosa remodeling possibly partly through activating JNK signal transduction pathway.

Objective To investigate the effects of 3 different ventilation methods,including conventional mechanical ventilation (CMV),high frequency oscillatory ventilation(HFOV) and partial liquid ventilation (PLV),on the changes of inflammatory factors and pulmonary surfactant associated protein A (SP-A) in bronchoalveolar lavage fluid (BALF) in newborn piglets with acute lung injury(ALI).Methods Twenty-four newborn piglets,no more than 3 days old,were enrolled.After ALI made with saline lavage(38 ℃,35 mL/kg),newborn piglets were randomly assigned to 4 groups:control group (n =6,no ventilation),CMV group(n =6),HFOV group(n =6),and PLV group(n =6).Piglets were sacrificed after being ventilated for 24 h.Tumor necrosis factor-α (TNF-α),interleukin-8 (IL-8),interleukin-1 (IL-1) and SP-A in BALF were measured quantitatively by using enzyme-linked immunosorbent assay.Results In 3 groups using different ventilation methods,the population mean of TNF-o,IL-8,IL-1 and SP-A were statistically different (all P =0.000).SP-A in PLV group and HFOV group were higher than that in CMV group (all P ＜ 0.05),while IL-8,IL-1 and TNF-α in PLV group were lower than those in CMV group (all P ＜ 0.05),IL-8 and TNF-α in PLV group were lower than those in HFOV group (all P ＜ 0.05),IL-8 and TNF-α in HFOV group were lower than those in CMV group (all P ＜ 0.05).Conclusions Pulmonary inflammatory reaction was different in 3 ventilation groups.Compared with CMV and HFOV,PLV attenuated inflammatory reaction,so it could increase the expression of SP-A and decrease the degradation of SP-A.

In this study, CD133+ subpopulations were isolated from 41 primary colorectal cancer tissues, the proliferation and cell cycle distribution of the cells were examined without in vitro expansion, and then compared to those of cell lines. The detection of CD133 in colorectal cancer tissues, isolation of CD133+ and CD133- epithelial subpopulations, Ki-67/DNA multiparameter assay and cell volume analysis were flow cytometrically conducted. The results showed that Ki-67 expression was correlated with CD133 level in primary cancer tissues, while cell cycle G2/M phase distribution or clinicopathological characteristics was not. In addition, the CD133+ cells showed larger cell volume and higher Ki-67 expression as compared with CD133- cells. But there was no statistically significant difference in G(2)/M phase distribution between the two subpopulations. Our results demonstrated that the CD133+ subpopulation in colorectal cancer tissue contained more actively cycling and proliferating cells, which was not correlated to clinicopathological factors but might contribute to tumor progression and poor clinical outcome.
